The thing that 180/15 mean in this context is the price of one ticket.

The quotient based on the information is $12.

The sixth-grade science club needs to raise $180 in order to visit a science museum. Since the price of each ticket is the same, the total sum of money required by the sixth-grade science club is 180, which is the dividend.

The number 15 serves as the divisor and represents the total amount of tickets required. The outcome of the division is the quotient. The ratio is $12. Therefore, the price of one ticket is the quotient.

Using statistical study, the steps are define the research question, selecting the sample, collect data, analyze the data, interpret results, report findings and draw conclusions.

A statistical study, also known as a statistical analysis or statistical survey, is a method of collecting, analyzing, and interpreting data in order to make inferences about a larger population. The goal of a statistical study is to extract information from a sample of data in order to make generalizations or predictions about a population.

Here are the seven steps for conducting a statistical study:

1.

Define the research question and objectives: Clearly define the research question and objectives of the study. In this case, the research question would be "Does eating before bed influence sleep patterns?"

2.

Select a sample: Select a sample of participants who will be included in the study. The sample should be representative of the population of interest and should be chosen using a random sampling method.

3.

Collect data: Collect data on the sleep patterns and eating habits of the participants in the sample. This could include measures such as sleep duration, sleep quality, and timing of last meal.

4.

Analyze the data: Use statistical methods to analyze the collected data. This could include comparing the sleep patterns of participants who eat before bed to those who do not, and determining if there is a significant difference between the two groups.

5.

Interpret the results: Interpret the results of the analysis, and determine if there is a statistically significant relationship between eating before bed and sleep patterns.

6.

Report the findings: Report the findings of the study, including a description of the research question, methods, results, and conclusions.

7.

Draw conclusions and make recommendations: Draw conclusions based on the results of the study, and make recommendations for future research or practical applications.

Please note that this is a general outline and the actual study may have different steps depending on the specific design, complexity and type of research.

The value of x is 8  

If all of the corresponding sides and angles of two triangles are identical, then those triangles are said to be similar triangles. In similar triangles, the ratio of the corresponding sides will be equal.

If two triangles ΔABC and ΔXYZ are similar triangles the ratio of the corresponding sides will be equal

=> AB/XY = BC/YZ = AC/ZX

Here we have

ΔDEF and ΔABC  

From both triangles,

The ratio of corresponding sides = DE/AB and FD/AC

As we calculate,  [tex]\frac{19.2}{3.2} = \frac{39}{6.5} = 6[/tex]

Using Venn diagram, There are total 24 people who study Russian and Spanish.

A Venn diagram is a visual representation that makes use of circles to highlight the connections between different objects or limited groups of objects. Circles that overlap share certain characteristics, whereas circles that do not overlap do not. Venn diagrams are useful for showing how two concepts are related and different visually.

Given,

50 pupils study Russian.

31 pupils study Spanish.

23 pupils study neither Russian nor Spanish.

Total = 80

80 - 23 = pupils study either Russian nor Spanish.

Using venn diagram formula,

Step-by-step explanation:

The system of equations we need to solve is:

x + y = 36

x*0.05 + y*0.25 = 6.20

Solving that we will see that she has 22 quarters and 14 nickels.

First we need to define the variables:

x = number of nickels

y = number of quarters.

We know that there are 36 coins, so we can write the equation:

x + y = 36

And the total value is $6.20, so we can write the equation:

x*0.05 + y*0.25 = 6.20

Then we can write the system of equations:

x + y = 36

x*0.05 + y*0.25 = 6.20

Using the first equation we can isolate x to get:

x = 36 - y

Replacing that in the other equation we will get:

(36 - y)*0.05 + y*0.25 = 6.20

We can solve this for y.

1.8 - y*0.05 + y*0.25 = 6.20

1.8 + y*0.20 = 6.20

y*0.20 = 6.20 - 1.8

y = 4.4/0.2

y = 22

Then the value of x is:

x = 36 - 22 = 14

Answer:

(- 2, - 7 )

Step-by-step explanation:

x + 3y = - 23 → (1)

- x + 4y = - 26 → (2)

add (1) and (2) term by term to eliminate x

(x - x) + (3y + 4y) = - 23 - 26

0 + 7y = - 49

7y = - 49 ( divide both sides by 7 )

y = - 7

substitute y = - 7 into either of the 2 equations and solve for x

substituting into (1)

x + 3(- 7) = - 23

x - 21 = - 23 ( add 21 to both sides )

x = - 2

solution is (- 2, - 7 )

The monthly interest payment is calculated by multiplying the average balance by the monthly interest rate.

To find the monthly interest rate, we need to divide the annual interest rate by 12 (since there are 12 months in a year).

24% annual interest rate / 12 months = 2% monthly interest rate

Now that we have the monthly interest rate, we can calculate the monthly interest payment by multiplying the average balance by the monthly interest rate.

$375 average balance x 2% monthly interest rate = $7.50 monthly interest payment

So the monthly interest payment in this situation is $7.50

t-test is used to compare the sample means from two related groups.

As previously stated, these two tests should be applied to separate data structures. When data from two samples are statistically independent, the two-sample t-test is employed, but the paired t-test is used when data is in the form of matched pairs.

To compare sample means from two related groups, the dependent samples t-test is utilized. This signifies that the scores for both groups being compared were obtained from the same individuals. The goal of this test is to see if there is a difference between two measurements (groups). If you’re only looking at one group, use a paired t-test to compare the mean of the group over time or after an intervention, or a one-sample t-test.

The area of the parallelogram-shaped rice field is 1120 square meters and the perimeter of the rice field is 150 meters.

The area of a parallelogram can be calculated by multiplying the base (length of one side) by the height. In this case, the base is 40 meters and the height is 28 meters, so the area of the rice field is:

40 meters x 28 meters = 1120 square meters

To find the perimeter of a parallelogram we add the four sides, two sides are 40 meters and the other two sides are 35 meters so the perimeter will be:

40 + 40 + 35 + 35 = 150 meters

So, around Pak Tani's rice field is 150 meters.

An angle is said to have a measure of 1 radian if it is subtended at its center by an arc of length 1 unit in a unit circle.

Since the triangle exists an isosceles triangle, the base angles are equal.

The three interiors angles of the triangle are,

(3 x+47),(4 x+6),(4 x+6)

The sum of these three angles must equivalent to 180°.

(3 x+47)+(4 x+6)+(4 x+6)=180

We group like terms to get,

3 x+4 x+4 x=180-47-6-6

This simplifies to,

11 x = 121

We divide both sides by 11 to get,

It is possible to compute the value of cos 135 degrees by first creating an angle of 135° .The exact value is sin (135) = (√2)/2 .

It is possible to compute the value of cos 135 degrees by first creating an angle of 135° with the x-axis, and then determining the coordinates of the point (-0.7071, 0.7071) on the unit circle.

You need the following formula to determine the precise value of cos(135):

cos(a+b) = cos(a + b) - cos(a + b) - sin(a + b)

In this instance, then, it would be:

Cos (45 + 90) = Cos (135) = Cos (45)

Sin 90 = (2)/2 0 - (2)/2 1 = 0 - (2)/2 = - (2)/2. Cos 90 - Sin 45.

You need the following formula to determine the precise value of sin(135):

Cos b - Cos a + Sin b = sin (a+b) = sin a • cos b

Accordingly, sin (135) = sin (90 + 45) = sin 90 • cos 45 + cos 90 • sin 45 = (1 (2)/2) + (0 (2)/2) = (2)/2).

cos (135)= - (√2)/2
